This was a fun puzzle. It started off generously, with numerous cells able to be solved early. Then things came to a halt and it was some time before I spotted an XY-Wing. After the eliminations therefrom, remote pairs solved a cell. After more eliminations, remote pairs using the same two numbers solved another cell, and that broke open the puzzle.

For me, XY-Wings and remote pairs are more talked about than actually used, so the opportunity to solve a puzzle using both techniques was indeed a treat.

Keith, I can't re-create my position at any given point, but I'm pretty sure it was the c-a-d XY-Wing that I used to set r6c2=7. Then I used the 67 remote pairs twice to finish it off. In both cases, those pairs set cells = 8.
